Problems solved by technology

At present, the methods involved in all patents are aimed at the preparation of nano-silica material powder and block, and it is impossible to efficiently prepare nano-silica powder material thin felt vacuum insulation panels, and it is difficult to meet its engineering requirements as a general-purpose thermal insulation material. Preparation and Use Requirements
At the same time, due to the low preparation efficiency, the production cost of airgel as a material is relatively high, which causes great difficulties for popularization and application.

Abstract

The invention discloses a vacuum insulating board made of a fiber reinforced nanometer powder material and a preparation method of the vacuum insulating board. The vacuum insulating board is composedof three parts of a core plate, a barrier film, a getter and a vacuum protection surface layer; and the core material is formed by continuous reinforced fibers and a nanometer silicon dioxide powder material, wherein the continuous reinforced fibers are selected from one or two of micro-glassfibers and carbon fibers. The preparation method comprises the following steps of preparing nanometer silicon dioxide into a wet gel solution by adopting a sol-gel method, then soaking the continuous reinforced fibers with the wet gel solution, then performing ageing, solvent exchange, modification treatment and pH regulation, finally, performing ambient pressure drying to prepare a fiber reinforced nanometer powder composite cotton felt material, and then adopting a stainless steel sheet to perform coating with a tailless vacuum technology to obtain the vacuum insulating board. The material expands the application field of nanometer silicon dioxide and can be used as thermal and sound insulation materials, fire-fighting fireproof and heat insulation materials and the like.

Description

technical field [0001] The patent of the invention relates to the field of vacuum insulation panels, in particular to a vacuum insulation panel made of fiber-reinforced nano-powder material and a preparation method thereof. technical background [0002] Vacuum insulation panel (VIP board) is the abbreviation of Vacuum Insulation Panel in English. It is a kind of vacuum insulation material. It is composed of filling core material and vacuum protection surface. The coefficient can be greatly reduced, less than 0.003W / m·K, and it does not contain any ODS materials. It has the characteristics of environmental protection and high efficiency and energy saving. It is currently the most advanced high-efficiency thermal insulation material in the world. VIP, a new type of super-strong thermal insulation material, is being paid attention to by merchants, and the market prospect is broad. The structure of the vacuum insulation panel includes a core material, a barrier film and a gette...
